###  Energy Solutions



#### Solar Energy
Solar energy is the fastest-growing self-sustainable energy industry in India. Every year India gets 5000 Trillion kWh per year which is the highest in terms of energy per square feet in the whole world. India produced around 50.13 TWh of solar electricity in 2019. Below we are trying to get requirements and possibilities of using solar energy in off-grid areas. 
- 5.4×3.25 ft solar panel can produce 300 W/h.
- Considering 8 hours of sunlight availability in summer we can produce 2.4 kWh/day.	
-  If we have roof space of 1100 sq feet out of which 700sq feet is available for pannels installation,
    - Number of solar panels can be used is approximately 23 with regular spacing 
    - Thus, max power that can be generated = 55 kWh/day considering whole terrace space to be used
- Cost of each solar panel of average quality ≃ 12,000 Rs
- Total cost of solar panels ≃ 2,76,000 Rs
- Reliability of this solution depends on weather conditions, in summer it is 90% reliable while in other seasons it is relatively less reliable.

#### Organic Energy
India produces more than 350 million tonnes of organic waste every year. This waste can make 18000MW of electricity every year. Usually, this form of energy production is more of community-based energy production than individuals. Below are the possibilities and requirements for organic energy in India. 
- Size calculations for fixed dome (hemisphere design) biogas plant:
    - Plant Diameter = 2.4m
    - Plant Volume = 3.62 cu.m
    - Digester Volume = 2.90 cu.m
    - Gas Storage Volume = 0.72 cu.m
    - Rated Daily Gas Production = 1.21 cu.m/day
- Different feed stocks can be used for biogas production like dung, night soil, poultry manure, dry leaf.
- For a plant size of 3.62 cubic meters if only cattle dung is taken as feed stock, approximately 4 cattles are required (considering a cattle produce 10 kg of dung/day on average)
- 1 cu.m of biogas would produce 4.698 kWh of electricity.
    - Daily electricity production => 4.698×1.21 = 5.68458 kWh 
- Fabrication cost for this biogas plant ≃ 22,000 Rs.
- Fixed Cost of the plant = 0.71 Rs/hr
- Operational Cost = 1.31 Rs/hr
- To produce 1.21 cubic meters of biogas, the plant needs to be operative for atleast 15 hours/day
- Therefore daily maintenance cost => 2.02*15 = 30.03 daily and 900 Rs in a month whereas construction cost is one time investment which is 22000 Rs approximately.

#### Hydro Energy
As the name suggest Hydro Energy stands for energy using following water. Below are the possibilities and requirements for Hydro energy in India.
- Around 60% of all renewable electricity is generated by hydropower. 
- The sector produces about 16% of total electricity generation from all sources.
-  Hydropower installed capacity reached 1,330 gigawatts (GW) in 2020 as generation hit a record 4,370 terawatt hours (TWh)
-  Energy Calculation:
    P=m×g×H_net×η
    P- power(Watts), g=9.81m/s^2 
    H_net= the net head. This is the gross head physically measured at the site, less any head losses. To keep things simple head losses can be assumed to be 10%, so
    H_net=Hgross x 0.9
    N is efficiency, For a typical small hydro system the turbine efficiency would be 85%, drive efficiency 95% and generator efficiency 93%, so the overall system efficiency would be: 0.85 x 0.95 x 0.93 = 0.751 i.e. 75.1%
    If we had  low gross head of 2.5 m then
    H_net= 2.5x0.9 = 2.25m.
    For a small hydra, assuming turbine could take max flow = 3 cu.m/s= 3000 ltr per sec.
    Power (W) = m x g x Hnet x η = 3,000 x 9.81 x 2.25 x 0.751 = 49,729 W = 49.7 kW

#### Power through treadmill
The treadmill's maximum output is 200W an hour. Considering, 4 hours workout on treadmill by whole family, per day power generation = 4×200 Watts hour.
Thus, 0.8 kW-h per day can be generated by treadmill.

#### Piezoelectricity 
- The power generated by the vibration of the piezoelectric is to be a maximum of 2mW, and provide enough energy to charge a 40mAh button cell battery in one hour. 
- Piezoelectric materials form transducers that are able to interchange electrical energy and mechanical motion or force.
- Output voltage from 1 piezo disc is 13V. Thus the maximum voltage that can be generated across the piezo tile is around 39V.
- Cost of Installation  : The piezoelectric sheets of the same material currently cost $165 in bulk from Piezo Systems (for 100 sheets of 10.64 cu. cm each), the cost per cu. cm of this material is about $0.155 or 11.47 Rs

#### Geothermal Energy
Home systems can’t generate electricity like Industrial-scale geothermal power plants, but they can save electricity by replacing conventional home heating and cooling with more efficient equipment.
##### Geothermal heating and cooling system:
- In the ground: A water-filled, closed-loop of 1-inch high-density polyethylene (HDPE) pipe ferries heat between the earth and the house. Pipes descend 4- to 6-inch-diameter vertical wells (the number and depth depend on the house's site and size) and bring lukewarm water.
- In the house: Pumps cycle water through the pipe loop to the heart of the system: the geothermal unit, which acts as furnace and air conditioner. This machine uses refrigerant and temperate water from the underground pipes to heat or cool air. The air is then circulated through standard ductwork.

- Cost of installation for a closed-loop horizontal system ≃ 7,00,000 Rs
- The cost depends on the house’s site. Although the upfront installation cost of geothermal systems is high, ground source heat pumps are much more efficient than traditional heating and cooling systems. They can achieve a Coefficient of Performance (COP) of 3-5, which means that with every unit of energy used by the system to power itself, it’ll produce 3-5 units of heat for the home.

<cen>ter>A typical demand curve on an average day in India</center>

- Total energy required to be stored
    - Averaging to get per capita peak demand, 136 W
    - Multiplying by 5 assuming a family size of 5, 680 W
    - Assuming + 50% percentage change for day to day variations, maximum possible energy demand required to be produced = 1020 W
    - Number of no-sun hours = 15 (peak winters)
    - Total energy required from the battery over a day = 15 KWh
- Excess energy would need to be produced in the afternoon to meet current requirements and the rest of the energy stored in batteries to be used in evening and night.
- Battery storage is a cost effective and efficient way to store energy.
- Li ion batteries among them are relatively cheap, low profile and suited for other needs. In off grid we would need more frequent charging and discharging cycles than being dependent on grid electricity and for that we prefer Li ion batteries over Lead acid batteries.
- Calculations for Lithium ion batteries
    - 1kg can store 150Wh of energy
    - Total amount required = 15KWh(Total requirement to store)/150Wh = 100kg
    - Cost of Li ion battery = 100 Rs/kg
    - Total Cost = 100×100 =10,000 Rs

Specifications:
Electrochemical storage (batteries) 
- Lithium-ion (LMO, NMC, NCA, LFP)
- Lead acid (Flooded, VRLA) 
- Nickel based (NiCd)
- Flow (RFB, HFB)
